[issue1431] pth files not loaded at startup
Giambattista Bloisi added the comment: What I meant for recursively was not to scan the full directory tree, but just to scan entries that have been added to the os.path. I think that this was the original intention as http://docs.python.org/inst/search-path.html states: Any directories added to the search path will be scanned in turn for .pth files. Also http://docs.python.org/lib/module-site.html states: For each of the distinct head-tail combinations, it sees if it refers to an existing directory, and if so, adds it to sys.path and also inspects the newly added path for configuration files. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1431 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1433] marshal roundtripping for unicode

[issue1438] Calling base class methods is slow due to __instancecheck__ override in abc.py
New submission from Guido van Rossum: [Guido] I've noticed that abc.py's __instancecheck__ gets called a lot at times when I don't expect it. Can you research this a bit? [Amaury] In classobject.c, method_call() calls PyObject_IsInstance() on the first arg when the method is unbound. This happens a lot in io.py, each time the code calls a base class method. [Guido] I wonder if we should get rid of this isinstance check. It is only used to be able to issue a pedantic error message. Perhaps we could even get rid of unbound methods, and just return the underlying function object instead of creating an unbound method object. This should make things a bit faster. -- messages: 57461 nosy: gvanrossum severity: normal status: open title: Calling base class methods is slow due to __instancecheck__ override in abc.py versions: Python 3.0 __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1438 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1433] marshal roundtripping for unicode
Guido van Rossum added the comment: I think this is unavoidable. Depending on whether you happen to be using a narrow or wide unicode build of Python, \U may be turned into a pair of surrogates anyway. It's not just marshal that's not roundtripping; the utf-8 codec has the same issue (and so does the utf-16 codec I presume). You will have to code around it.

[issue1436] logging.config.fileConfig, NameError: name 'RotatingFileHandler' is not defined
Vinay Sajip added the comment: This is not a bug: I think you are missing something. In the first example (interactive usage), the lines import logging and import logging.handlers do not magically introduce RotatingFileHandler into your interactive session's globals. To do this, you would have to say from logging.handlers import RotatingFileHandler. An analogous example unrelated to logging: ActivePython 2.4.3 Build 12 (ActiveState Software Inc.) based on Python 2.4.3 (#69, Apr 11 2006, 15:32:42) [MSC v.1310 32 bit (Intel)] on win32 Type help, copyright, credits or license for more information. import httplib HTTP Traceback (most recent call last): File stdin, line 1, in ? NameError: name 'HTTP' is not defined httplib.HTTP class httplib.HTTP at 0x00A759F0 In the second example (using fileConfig), the documentation in http://docs.python.org/lib/logging-config-fileformat.html clearly states that the class and arguments are evaluated using the logging package's namespace. This means that for a handler defined in the logging package itself (such as StreamHandler) no qualification is required, but for a handler defined in the handlers subpackage, you should specify handlers.RotatingFileHandler in the configuration file rather than RotatingFileHandler or logging.handlers.RotatingFileHandler. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1436 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1431] pth files not loaded at startup
Brett Cannon added the comment: For what you meant by recursion, that makes more sense. But as for whether this is correct or not, read the next paragraph in the site docs (http://docs.python.org/dev/library/site.html#module-site). It says A path configuration file is a file whose name has the form package.pth and exists in one of the four directories mentioned above. So the newly added path is the four paths mentioned in that paragraph (e.g., the ones that involve sys.prefix and sys.exec_prefix. So the docs do not suggest that any recursive check is done, nor does it need to worry about pre-existing directories. It just needs to check site-packages locations and site-python. If site.py is not checking those directories, it is a bug, otherwise I think the current behaviour matches the documentation. -- assignee: - brett.cannon __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1431 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1431] pth files not loaded at startup
Giambattista Bloisi added the comment: This make sense. I hope I'm not annoying you. But what I did was to read (http://docs.python.org/inst/search-path.html) before reading (http://docs.python.org/dev/library/site.html#module-site) as the latter is referenced by the first via a html link. The part of my interest of the first document says: The expected convention for locally installed packages is to put them in the .../site-packages/ directory, but you may want to install Python modules into some arbitrary directory. For example, your site may have a convention of keeping all software related to the web server under /www. Add-on Python modules might then belong in /www/python, and in order to import them, this directory must be added to sys.path. There are several different ways to add the directory. The most convenient way is to add a path configuration file to a directory that's already on Python's path, usually to the .../site-packages/ directory. Path configuration files have an extension of .pth, and each line must contain a single path that will be appended to sys.path. (Because the new paths are appended to sys.path, modules in the added directories will not override standard modules. This means you can't use this mechanism for installing fixed versions of standard modules.) So the gobolinux maintainer did: it added a file into this dir and it is actually parsed and some dirs are appended to sys.path. And after that the document says what already quoted: Paths can be absolute or relative, in which case they're relative to the directory containing the .pth file. Any directories added to the search path will be scanned in turn for .pth files. See site module documentation for more information. So why repeat here that some other directories will be scanned for pth files, while you describe the accepted format for paths in .pth files? If the only scanned directories are the ones already cited (a directory that's already on Python's path), IMO there is no need to specify further, unless you mean that the single path appended to sys.path that you are describing will be scanned *in turn* for .pth file. On the other hand the second document doesn't say explicitly that the *only* scanned directories are the ones derived from sys.prefix and sys.exec_prefix. Indeed on darwin (Mac Os X) additional directories are actually parsed. __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1431 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1134] Parsing a simple script eats all of your memory
Viktor Ferenczi added the comment: This bug prevents me and many others to do preliminary testing on Py3k, which slows down it's development. This bug is _really_ hurts. I've a completely developed new module for Py3k that cannot be released due to this bug, since it's unit tests are affected by this bug and would crash the user's machine. Sadly I've not enough free time and readily available in-depth knowledge to fix this, especially after the first attempt was not perfect, which shows that it may be a bug that cannot be fixed by correcting a typo somewhere... :-) __ Tracker [EMAIL PROTECTED] http://bugs.python.org/issue1134 __ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue1442] pythonstartup addition of minor error checking
New submission from Joseph Armbruster:
Trunk revision: 58963
Description: No warning or error is reported it a file pointed to by
PYTHONSTARTUP is not readable.
Request: To display a warning so that the user may be notified.
Note: Errors that may occur in PyRun_SimpleFileExFlags are being cast
away, may be worthwhile to report an error for those as well (unless
this was avoided for good reason :-)
Suggestion:
static void RunStartupFile(PyCompilerFlags *cf)
{
char *startup = Py_GETENV(PYTHONSTARTUP);
if (startup != NULL startup[0] != '\0') {
FILE *fp = fopen(startup, r);
if (fp != NULL) {
(void) PyRun_SimpleFileExFlags(fp, startup, 0, cf);
PyErr_Clear();
fclose(fp);
}
else {
fprintf(stderr,Warning: Could not read startup file %s\n,startup);
}
}
}
